Title: Improved arrangement for the frequency modulation of micro-wave generators
IPC: H03C3/28
Filed: 1945-11-14
Abstract: 599,061. Frequency modulation. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING AKT.-GES. Nov. 14, 1945, No. 30434. Convention date, July 14. [Class 40 (v)] A micro-wave transmitter is frequencymodulated by a piezo-electric crystal which bends or flexes under the influence of the modulating voltage and is provided with a conductive coating which forms a variable capacity in association with one or more conductors extending outwards from the microwave generator. The generator G has its oscillatory system associated with a pair of Lecher rods L extending through the envelope and connected at their outer ends to capacity plates K carried on an insulating disc P. The crystal S which may be formed of two superposed square or rectangular slices is coated on one side with a conducting band B lying opposite the plates K and moving relative thereto as the crystal bends. The capacity across the ends of the Lecher pair L is thus varied, and the frequency of the generator G correspondingly modulated. The portions of the crystal have their crystal axes suitably oriented, and the modulating voltage is applied between their connected outer conducting coatings and the intermediate coating. The modulating voltage may be applied through rods M and clamps H which hold the motionless corners of the crystals. The natural frequency of the crystal lies above the upper limit of the modulating frequency. The materials of which the rods L, M are formed may have such expansion coefficients as to compensate for temperature changes. The conducting band B may be highly polished so as to reflect heat from the generator and reduce rise in temperature. The length of the rods L should be approximately half a wave-length, or a multiple thereof. In an alternative arrangement, the crystal is rod-shaped and is held firmly in the middle.

Patent GB-1541776-A (GB)
Title: Preparation of foamed plastics materials with combustion characteristics
IPC: C08G18/54
Filed: 1977-07-22
Abstract: An aqueous solution of water-soluble amino resin precondensates is condensed with organic isocyanates, firstly amines and/or organometallic compounds being added to the organic isocyanate, and simultaneously, but separately from one another, a solution of the amino resin precondensate and acidic curing catalysts then being added to the mixture. Foaming inevitably occurs during this operation. The process enables the preparation of, in particular, lightweight foams without the use of particular foaming (blowing) agents. Three different catalyst groups act in concert, with no mutual inhibition. An appropriate choice of the amino resin component, the water content, the amount of polyisocyanate and the combination of the acidic, basic or organometallic catalysts makes it possible to produce, in an economical manner and in a single step and a short production time, foams having good fire and insulation properties which cure tack-free without further thermal aftertreatment.

Title: Improvements relating to the prevention of accumulation of ice or other solids in air inlet ducts in aircraft
Inventor: STANTON FRANCIS PATRICK
IPC: B64D15/04
Filed: 1957-10-03
Abstract: 893,953. De-icing aircraft. BRISTOL SIDDELEY ENGINES Ltd. Sept. 11, 1958 [Oct. 3, 1957], No. 31043/57. Class 4. [Also in Groups XXVI and XXVIII] In an air inlet duct 1 of an aircraft, having a bend 4, means are provided for preventing the accumulation in the bend of solid material such as ice, coherable particles of which are carried in suspension in the gaseous flow. The means comprises a nozzle or nozzle system 5 located somewhat upstream of the beginning of that part of the wall of the duct upon which solid material is liable toaccumulate and directed substantially along the wall in the direction of the fluid flow, the nozzle or nozzle system being connected to a source of gaseous fluid under pressure so that a sheath of gaseous fluid under pressure is produced on the outer wall of the bend. The velocity of the sheath of fluid is sufficiently greater than the flow of the air in the duct so that deposition of solid material on the outer wall of the bend is prevented. The invention is shown in Fig. 2 applied in the case of an aircraft gas turbine propulsion engine. The engine comprises an annular air intake 10 which is connected to the intake of the compressor 12 by a series of U-bend ducts 11. To prevent the formation of ice deposits on the outer walls of the U-bends, each bend is provided with a sytem of narrow slit convergent nozzles 20 which are supplied with air under pressure from the manifold 21. Air for this purpose is tapped from the engine compressor 12 through duct 22 and control valve 23. The pressure ratio across the nozzles 20 is of the order of 2: 1. The air tapped from the compressor may be cooled before use in the nozzles 20 so as not to impair the efficiency of the compressor. The nozzles 20 may be of convergent-divergent form and the pressure may be such that the velocity of discharge at the nozzles is greater than Mach 1.

A crop store wherein crop is fed under pressure into the storage space is provided with crop retaining members located near the opening of the store and means for indicating the pressure exerted by the stored crop on the wall of the store. The crop store 1 (Fig. 1) is formed with circular sections 2 each made of three arcuate sections joined by longitudinal beams. Crop deposited on conveyers 31 and 33 is transported by conveyer 32 and an auger (not shown) into the supply channel 10 under the action of reciprocatory ram 22 driven by electric motor 28. Electric motor 36 reciprocates pressure member 11 to force crop into the storage space. A displaceable wall 43 inside the cylindrical sections is provided on its periphery with three equally spaced wheels coinciding with the longitudinal beams, the wheels being driven by an electric motor mounted on the centre of wall 43. The wheels cooperate with a toothed rack on the beams. To effect discharge a vertical worm conveyer secured to wall 43 loosens the crop and the displaceable wall forces it through the exit flaps on the side of the cylindrical sections 2. Pressure indicating devices (Fig. 8) comprise two segments 82 forming part of the wall, pivoted at their remote ends 83A and covered at their adjacent ends by a screening 83 that can slide relative to portion 82. The length of protrusion of pin 88 indicates the crop pressure.
